How the formula works
Both nanowatt and attowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanowatts by 1.000000e+09 to get attowatts. To reverse the conversion, multiply a attowatt value by 1.000000e-09 to get back to nanowatts.
Frequently asked questions
What is Nanowatt (nW)?
A Nanowatt (nW) equals 1e-09 watt(s), a scaled unit of electrical power used for nano-scale electrical work.
What is Attowatt (aW)?
An Attowatt (aW) equals 1e-18 watt(s), a scaled unit of electrical power used for atto-scale electrical work.
How do I convert nanowatts to attowatts?
Multiply the nanowatt value by 1.000000e+09 to get the equivalent in attowatts. For example, 5 nW × 1.000000e+09 = 5.000000e+09 aW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+09 is an exact, non-rounded value.
Can I convert attowatts back to nanowatts?
Yes. Divide the attowatt value by 1.000000e+09, or multiply it by 1.000000e-09, to get nanowatts.
